How to Upcycle a Metal Filing Cabinet

Reusing and repurposing old furniture is a sustainable and creative way to give new life to something that may otherwise end up in a landfill. Metal filing cabinets are extremely versatile items that can be upcycled in many different ways with just a little imagination. Upcycling a metal filing cabinet requires some tools and supplies but can lead to beautiful results. Read on to learn everything you need to know about how to upcycle a metal filing cabinet.

Assess the Filing Cabinet’s Condition

Before beginning your upcycling project, thoroughly inspect the filing cabinet to determine what kind of shape it’s in. Look for any rust, dents, missing handles or hardware, and drawers that stick or don’t open properly. Make note of these issues as you may need to address them before moving forward.

Test each drawer to make sure it opens and closes smoothly and see if the locking mechanisms are still functioning. Inspect the glides or rollers on the bottom of the drawers to ensure they are sturdy. Check for any holes, significant scratches or other cosmetic damage.

If the filing cabinet is structurally sound with only minor flaws, it can likely be upcycled successfully. However, major damage or corrosion may require more restoration work.

Clean the Filing Cabinet

Once you’ve assessed the condition, it’s time to clean the filing cabinet thoroughly. This removes built-up dirt, grime, dust and any rust.

Supplies needed:

• Drop cloths or old sheets
• Rubber gloves
• Eye protection
• Mild detergent or degreasing cleaner
• Scrub brush and/or steel wool
• Clean cloths or paper towels
• Bucket of warm water
• Tarp or outdoor working space (for large cabinets)

Start by removing all drawers from the cabinet and setting hardware like handles aside in a safe spot. Lay down drop cloths in your work area to protect floors and nearby surfaces. Put on gloves and eye protection.

Fill your bucket with warm water and add a small amount of mild detergent or degreasing cleaner. Dip your scrub brush into the water and scrub all surfaces of the drawers and cabinet box, paying close attention to areas with grime buildup.

For stubborn dirt or rust, use steel wool to gently scrub the affected areas. Avoid applying too much pressure as this can cause unsightly scratches.

Rinse surfaces thoroughly with clean water as you work to remove all soap residue. Dry with clean cloths or paper towels. Repeat on all drawers and the cabinet box.

Once fully cleaned, inspect for any additional flaws like dents or holes that may need repairing later. Allow all components to fully dry before moving to the next steps.

Repair Damage and Restore Surfaces

Now is the time to make any necessary repairs so the filing cabinet is restored to its best possible condition. Address dents, holes, sticking drawers, locking mechanisms and any other issues found during inspection and cleaning.

Dents

For minor dents, try gently massaging the metal from the inside to smooth it out. Place a block of wood on the inside of the dent and tap it with a hammer to push the metal back into shape.

Rub the area with fine grit sandpaper to blend cracks or uneven spots. Fill deeper dents with auto body filler, allow to dry fully, then sand flush. Apply primer and sand again before painting.

Holes and Corrosion

Fill small holes with automotive body filler, allow to dry, and sand smooth. Larger holes may need a patch of similar gauge metal screwed into place before applying filler.

Remove any rust or corrosion using 80-100 grit sandpaper. Wipe away dust then apply a rust converter primer to prevent future rust. Allow to dry fully before filling dents or painting.

Sticking Drawers

Take sticky drawers completely out of the rails and inspect the glides or rollers. Replace any that are cracked, broken or missing. Clean buildup off intact glides with steel wool.

Lubricate glides and slide rails with a wax candle or dry lubricant spray. Reinstall drawers and test to make sure they open smoothly.

Locking Mechanisms

Disassemble locking mechanisms, clean thoroughly removing any dirt or debris. Lubricate with penetrating oil or powdered graphite for locks. Replace any broken or missing parts. Reinstall and test locks.

Sand and Prime the Filing Cabinet

Once repairs are complete, scuff sand all surfaces with 220 grit sandpaper to rough up the finish. This helps primer and paint adhere properly. Use a sanding sponge for hard to reach spots.

Thoroughly dust off all sanding residue using a tack cloth. Apply 1-2 coats of metal primer, allowing to fully dry between coats according to the manufacturer’s instructions.

The primer fills any tiny scratches or imperfections and creates a surface paint can grip to. Be sure to get full coverage, including the edges and underside of drawer panels.

Add Paint or Other Finishes

Now the fully prepped filing cabinet is ready for painting, staining, waxing or any other type of finish. Consider how you want the final piece to look and function when selecting products.

Paint

For a bright, bold look use a high quality enamel spray paint in your desired color. Multiple thin coats allow the paint to fully cure resulting in a smooth, hard finish. Lightly sand between coats.

Stain

Penetrating stains enhance the natural look of the metal while still providing protection. Wipe on gel stains work well for vertical surfaces like cabinet sides. Finish with a clear polyurethane for added durability.

Chalk Paint

This thick paint adheres well to metal without requiring primer or sanding. The matte finish pairs nicely with glazes to create an aged, vintage look. Can be waxed or sealed for protection.

Wax

Apply paste wax or a wax-oil blend by hand to seal the metal while retaining its industrial aesthetic. Buff to desired sheen. Reapply wax periodically for ongoing protection.

Rust Activator

This acidic liquid creates an instant rust patina on bare metal. Wax or seal after for permanent rust effect. Use gloves and work outdoors.

Wallpaper

Adhere a wallpaper pattern using decoupage medium for a fun, graphics-inspired design. Seal with polyurethane for durability.

Apply your chosen finish carefully following all product instructions. Fully finish the exterior and interior surfaces of the cabinet and drawers for maximum protection and aesthetics.

Replace Hardware

Reinstall any original handles and hardware you set aside after a thorough cleaning and polish. Check that screw holes aren’t stripped or enlarged.

Consider switching out old hardware for newer pulls, handles and knobs to give the filing cabinet a fresh updated look. Brass, chrome and nickel finishes pair nicely with painted metal.

Stick with metal hardware to match the weight and durability of the filing cabinet. Measure spacing and holes carefully for a seamless installation.

Add Lighting

One way to really make your upcycled filing cabinet stand out is by adding lighting. This not only illuminates the interior but creates visual interest.

Battery-Operated Strings

Affix battery-operated LED light strips to the upper interior edges using adhesive. Hide batteries in top drawers. Add a remote to control.

Wired Cabinets

Have an electrician wire in interior lighting, under cabinet lighting or sconces. Hardwire into an outlet or install a plug. Use touch switches.

Removable Options

Portable battery-powered pucks, stick-on lights or desk lamps can be placed inside or on top of cabinets to provide removable lighting.

Give the Filing Cabinet New Purpose

Now for the fun part – turning your restored filing cabinet into something completely new! Consider how you want to repurpose it when making any structural changes.

Kitchen Pantry

Convert to a narrow freestanding pantry by removing top drawers and installing cabinets up top for food storage. Paint or stain to match kitchen decor.

Bar Cabinet

Take off top drawers and add a wood countertop for an inviting drink station. Fit remaining drawers with wine glass racks or beverage chilling systems.

Bathroom Storage

Paint glossy white and fill lower drawers with rolled towels and upper drawers with toiletries. Top with a basket or decorative tray for a spa-like look.

Craft Storage

Accessories like pegboards, small bins and acrylic risers keep craft supplies organized. Paint a fun color and label drawers for ultimate functionality.

Office Storage

Upcycle into a vertical filing system by removing hanging file bars from large bottom drawers. Use top drawers for supplies. Freshen up with new hardware.

The possibilities are endless when repurposing metal filing cabinets! Apply your creativity to give it new life.
